+# Path Normalization 403 Bypass Labs
+
+This repository contains different scenarios for bypassing 403s leverage path normalization inconsistencies which stem from deny rules e.g. configured in Nginx. This work is inspired by https://rafa.hashnode.dev/exploiting-http-parsers-inconsistencies.
+
+# Setup (1 Command!)
+
+* You can run each of the scenarios by navigating into the folder and simply executing `docker-compose up`
+
+# Scenarios
+
+### Flask
+
+* Goal: Access `/admin`
+* Problem: Nginx has a rule to deny access to `/admin` and blocks you
+* Bypass: E.g. visit `GET /admin\xa0` (note that you actually need to send the hex character, not the string `\xa0`)
